Compressed sensing Matlab code
no vote
Compressed sensing, compressive sampling, compressed sensing. As a new theory of sampling, it develops through signal sparse property, in conditions of far less than the Nyquist sample rate, using random sampling to obtain discrete samples of a signal and then reconstruction algorithm of nonlinear perfect reconstruction of signals. Theory of compressed sensing that is raised, it caused widespread concern in both academia and industry. In information theory, image processing, Earth Sciences, optics, imaging, pattern recognition, wireless communication, atmosphere and high attention to geological areas and was United States technology review awarded 2007 top ten scientific and technological advances. A signal through the randomly generated, according to the theory of compressive sensing, to sample its reconstruction, and final results were compared.

C/A code GPS satellites send a PN for rough location and captures GPS satellite is in fact a Gold code, that is made up of 2 10-level feedback shift register g-code generation. The bit width of the C/A code is bigger. Assuming that two sequences of bits wide with an error code of 1/10~1/100, then the corresponding range is 29.3~2.93m. With the development of modern science and technology, make range resolution is greatly increased. Easiest navigation receiver General of pseudorange measurements at resolutions up to 0.1M.

Power spectral estimation algorithm of L-D
4.0
Power spectral estimation, the youlawoke equation is particularly important, but for solving the youlawoke equation is rather complicated. This program provides an algorithm based on recursive L-D Jie Youla Walker equation, very good solution to calculate AR power spectrum estimation parameters and the variance of the input problem. Is a very good one. Very helpful for beginners.
